Psi Eridani, Latinized from ψ Eridani, is a star in the constellation Eridanus. With an apparent visual magnitude is 4.81, [ 2 ] it can be seen with the naked eye on a clear, dark night. Based upon an annual parallax shift of 4.41 milliarcseconds , [ 1 ] it is located roughly 740 light-years away from the Sun .
Delta Eridani, which is Latinized from δ Eridani, is the fifth-brightest star in the constellation of Eridanus.. The star is visible to the naked eye and has been observed to vary slightly in brightness between magnitudes 3.51 and 3.56, [2] although subsequent observations did not bear this out. [11]
53 Eridani (abbreviated 53 Eri), also designated l Eridani (l Eri), is a binary star in the constellation of Eridanus. The system has a combined apparent magnitude of 3.87. Parallax estimates made by the Hipparcos spacecraft put it at a distance of about 110 light-years , or 33.7 parsecs , from the Sun .
Tau 4 Eridani (τ 4 Eridani, τ 4 Eri) is a binary star system in the constellation Eridanus.It is visible to the naked eye with an apparent visual magnitude of 3.65. [2] The distance to this star can be estimated using the parallax method, which yields a value of roughly 300 light years.
